2.0 DESCRIPTION

As shown in DECA Aviation Modification Summary MS11120, the modification permits the installation of the
following:

1) A Latitude Iridium/GPS Antenna (quantity: 1, p/n: S5GIR1516RR-A2P-XTT-1, wt: 0.52 lbs,

5.03”x2.2”x0.72”height) installed on the upper fuselage of the Beechcraft models. The Iridium/GPS
antenna is an oval shaped low profile antenna requiring two 0.75” diameter skin penetrations. An Al Aly
2024-T3 external doubler is used, fastened with countersunk rivets. The antenna is fastened using #10-
32 countersunk screws.

• For the Beechcraft 200, 200C, 200CT, 200T, B200, B200C, B200CT, B200T, A200, A200C,
A200CT, the antenna is installed on the upper fuselage either:
A. above the main passenger door, between FS 285.188 & FS 291.875 (between the
centerline stinger and stringer 2R) or
B. between FS 165.125 & FS 175.25 (between centerline & stringer 2R or stringer 2L) or
C. between FS 236.125 & FS 246 (between centerline & stringer 2R or stringer 2L).
D. between FS 246 & FS 256.25 (between centerline & stringer 2R or stringer 2L).

2) An Alternative Latitude Iridium/GPS/WiFi Antenna (quantity: 1, p/n: 5G151624RRL-A2P-XTTT-1, wt: 0.5

lbs, 5.03”x2.2”x0.72”height) installed on the same upper fuselage of the Beechcraft models. Similarly,
the Iridium/GPS/WiFi antenna is an oval shaped low profile antenna requiring three 0.75” diameter skin
penetrations but due to the close proximity of the three penetrations an oval (2.50”x0.75”) skin
penetration is made instead. An Al Aly 2024-T3 external doubler is used, fastened with countersunk
rivets. The antenna is fastened using #10-32 countersunk screws.
